Richard Brian "Rick" Azari was a Mob Boss.
Prior the series, Azari was the right-hand man of crime boss Alonzo Torres. Upon Torres imprisonment at the hands of Tobias Fornell, Azari seized power and built his own criminal empire at the expense of the lives of many of Alonzo's former employees.
Azari would later be tried for murder twice, walking each time. Each case was initiated after an investigation by Fornell, who made Azari a personal priority.
NCIS Season 6Edit
Azari was due for a third murder trial in which Marine Sergeant Jack Kale was to testify against him as a witness. Azari ordered the murders of Robert Brewer and Michael Strauss, who witnessed the murder while trying to acquire cocaine. They were Kale's former squadmates. When confronted by Leroy Jethro Gibbs, Azari was confident he wouldn't go down. He was right; Strauss and Brewer were the only witnesses, having informed Kale later, thus making his testimony inadmissible.
Kale later approached Azari in front of the courthouse where he was set to be tried. Kale aimed a gun at Azari, wanting revenge. Azari declared that if Kale was going to shoot, he'd have done it already. In a display of spectacular arrogance, he repeatedly taunted Kale even as Fornell and Gibbs tried to talk him down, as he was confident the marine didn't have the conviction to pull the trigger. Kale gunned him down a moment later. Azari died gripping at Tobias Fornell, who showed no sympathy for the crime lord. It was later implied that Fornell deliberately allowed Kale to kill him, knowing that no trial would convict him.
